Technical details
An OS command injection vulnerability (CWE-78) exists in the /bin/ioos WireGuard CLI group handler at address 0x419a54, where the group_name parameter is embedded verbatim into a uci command string executed via system() without sanitization. An attacker can break out of the single-quoted context using a payload like a';CMD;' to inject arbitrary shell commands that run as root. Authentication is bypassed via localhost trust (IP-FROM spoofing) or the default admin credentials; the vulnerability is effectively unauthenticated on factory-default devices.
